RADIATOR-SH ELF.

SPECIFICATION forming part of Letters Patent No. 502,871, dated August 8, 1893.

Application tiled Jannaryr24, 1893. Serial No.459,574. (No model.)

To a/ZZ whom it may concern:

Be it known that I, ALBERT J. BENNETT, ofl

Woonsockct, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Radiator- Shelves; and I hereby declare that'the following is afull, clear, and exact description of the same, reference beinghad to the-accompanying drawings, forming part of this speciication.

This invention has reference to improvements in adjustable-shelves for radiators.

The object of the invention is to so construct a shelf, which is also adapted to serve as a foot-rest, that it may be adjnstably secured to the tube of a radiator in a convenient position.

The further object of t-he invention is to pro-v vide a shelf, or foot-rest, with a clampingdevice by which the shelf may be readily secured to a radiator and can be adjusted thereon.

The invention consists in the peculiar construction of the clamping-device and the combination therewith of a shelf, or rest, having a shank, as will hereinafter be more fully described and pointed out in the claims.

Figure 1 represents a top view of the improved shelf and clamp secured to a radiatortube. Fig. 2 represents an end view thereof. Fig. 3 represents an enlarged vertical sectional view of the clamp to more clearly indicate its construction.

Similar numbers of reference designate corresponding parts throughout.

In the drawings 5 indicates a shelf, or rest, formed of a grating, and 6 is a supporting and strengthening frame to which the shelf is secured. Extending from the frame is a shank 7 a part of which may form the central-brace of the frame 6. The clamp is furnished with jaws 8 and 9 which are shaped to grasp the radiator-tube 10; these jaws extend from the4 A through which a slot is formed which corresponds in shape with the cross-sectional shape of the shank 7; this bar is free to rotate in the perforations of the bases 11 and 12 and has a screw-thread 19 with which the checknut-20 engages and thus limits the longitudinal movement of the sliding-block 21 which is mounted on this end of the clamping-bar.

Pivoted to the block 21 are the cam-arms of the frame 22 provided with a handle 23, the bearing of the cam-arms against the outer surface of the base 12 serving to force the block 21 against the check-nut 2O and exerting a drawing-strain on the clamping-bar. The supporting-block 24 has a central-depression on its inner surface which is surrounded byan annular-ratchet adapted to engage with the ratchet 16 of the base 1l; this block is furnished'with the braces 25 and 26 and has a transverse-slot between the braces through which the shank 7 may, slide. The block 24 has also a slot, extending at right angles with that first mentioned, to receive the enlargement 18 of the clamping-bar. The jaws S and 9 having been secured to the radiator-tube l0 by the tightening of the screw 13, the shank 7 of the shelf is passed through the transverse-slot of the block 24 and through the slot in the enlargement 18 of the clamping-bar. The shelf is now adj usted at any desired angle with the radiator and the handle is brought to the position, shown in Fig. 1, on a line with the clamping-bar, thus clamping the shank 7 in the block 24 and drawing the ratchet of this block into engagement with the ratchet 16 of the base 11, which prevents the independent rotation 0f the block 24. The clamping ofthe shank 7 in the block 24 is an important feature as, when the shelf is used as a foot-rest and is inclined at a downward angle from, the clamp, the shank would otherwise slip from the block 24. The camarms 22 also serve to moresecnrely clamp the jaws 8 and 9 to the radiator-pipe.

Having thus described my invention, I

IOO

check-nut 2O and the sliding-block 21 pivoted between the cam-arms of the frame 22 which is provided with a handle, of the shelf 5, the frame 6 secured thereto,and the shank 7 adapt- 1 5 'ed to be clamped in the block 24, as described.

In witness whereof I have hereunto set my hand.

ALBERT J. BENNETT. Witnesses:
